CROSS-REFERENCE TO RELATED APPLICATION

This patent application claims the benefit of and priority to Chinese Patent Application No. 201810037062.8, filed on Jan. 15, 2018. The disclosure of this patent application is herein incorporated by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to a girder, and, more particularly, to a heavy duty girder for a modular system.

BACKGROUND

At present, a known heavy duty girder is used for constructing a modular system through supporting structural components, cables and various other heavy duty installation applications.

DE202012102463 discloses a girder in particular for mounting cables, which has a fastening or supporting profile that is hollow and has at least two opposite circumferential sides. The hollow profile also has an internally shaped mounting channel for receiving at least one slider on at least one peripheral side.

However, the mounting channel is disposed at a pair of sides of the girder, rather than at all sides of the girder, which cannot meet the multi-surface mounting requirements. Moreover, the bottom of the mounting channel on the girder is easily deformed when subjected to a great force.

SUMMARY

The present disclosure is directed to an innovation that overcomes the limitations of the known art and the problems that remain unsolved, by providing a heavy duty girder.

There is provided herein a heavy duty girder comprising: a plurality of outer sides and a mounting channel disposed on each of the outer sides and including a bottom surface and a pair of side surfaces, wherein each of the side surfaces has one end extending to the outer side by one or two bending portions including a first bending portion coupled to the outer side and a second bending portion coupled to the side surface, and the other end extending to the bottom surface by a third bending portion.

In a further embodiment, the bending direction of the second bending portion is opposite to or perpendicular to the bending direction of the first bending portion.

In a further embodiment, the second bending portion abuts against an inner wall of the hollow body.

In a further embodiment, a first channel width is formed between bending insides of each pair of the first bending portions, a second channel width is formed between each pair of the side surfaces, and a channel depth is formed between the bottom surface and a corresponding outer side.

In a further embodiment, the first channel width, the second channel width and the channel depth are configured for allowing accommodation of a bolt assembly, and access of a mounting tool to the mounting channel.

In a further embodiment, the first bending portion is formed with an anti-skidding track at a position facing the bottom surface.

In a further embodiment, the anti-skidding track is a toothed track.

In a further embodiment, the heavy duty girder further comprises a through hole passing through two opposing bottom surfaces.

In a further embodiment, the hollow body is formed integrally by sheet metal bending.

The heavy duty girder according to the disclosure provides an easy installation at four sides, achieves an adjustable, flexible solution for industrially heavy duty commercial applications, without the need for welding assembly of ball columns, cantilevers, suspensions or angle supports.

Moreover, the mounting track of the disclosed heavy duty girder provides an anti-skidding rail of the mounting channel to obtain greater bearing capacity while allow location of the mount.

These and other aspects, features, and advantages of the present disclosure will become more apparent from the detailed description of the preferred embodiments with reference to the drawings.

Referring now to FIG. 1, there is illustrated an exemplary embodiment of a heavy duty girder 100 according to the disclosure. The heavy duty girder 100 has a strip-shaped hollow body which is formed integrally by sheet metal bending. The heavy duty girder 100 includes a plurality of outer sides, preferably 4 outer sides, wherein each of the outer sides 120 is formed with a mounting channel 110 including a bottom surface 111 and two opposite side surfaces 112. It is not only easy to install, but also improve the rigidity of the girder body due to the fact that each side of the girder is formed with a mounting channel 110.

Referring now to FIG. 2, each of the side surfaces 112 has one end extending to the outer side by a first bending portion 113 and a second bending portion 114 and the other end extending to the bottom surface 111 by a third bending portion 115. The bending direction of the second bending portion 113 is substantially perpendicular to the bending direction of the second bending portion 114 (or the difference between two bending angles is about 90 degree), such that the side surface 112 is formed to be substantially perpendicular to the bottom surface 111. Preferably, the bended second bending portion 114 abuts against the inner wall of the hollow body. In other embodiments not shown in the drawing, the bending direction of the second bending portion 113 is opposite to the bending direction of the second bending portion 114, such that an acute angle is formed between the side surface 112 and the bottom surface 111.

Referring now to FIG. 3, optionally, each of the side surfaces 112 has one end extending to the outer side only by a first bending portion 113, and the other end extending to the bottom surface 111 by a third bending portion 115, such that an acute angle is formed between the side surface 112 and the bottom surface 111.

Referring now to FIG. 4, a first channel width (W1) is formed between bending insides 117 of each pair of first bending portions 113, a second channel width (W2) is formed between each pair of the side surfaces 112, and a channel depth (H1) is formed between the bottom surface 111 and the corresponding outer side 120. As shown in FIG. 4, the first channel width (W1) allows a bolt assembly 200 to pass through the bottom surfaces 111 for mounting and a sleeve (S) of the mounting tool to access the mounting channel 110 and twists the bolt assembly 200 when a through hole 130 is formed in the two opposite bottom surfaces 111. The figure shows the bolt assembly 200 is mounted at the upper and lower sides, but the person skilled in the art may envisage that the bolt assembly 200 can be mounted at the left side and right side, or at the upper side, lower side, left side and right side at the same time.

Moreover, the channel 110 depth (H1) is configured for allowing the screw nut of the bolt assembly 200 in the mounting channel 110 not to protrude beyond the outer side 120. The second channel width (W2) is configured for allowing the screw to snap in the mounting channel 110 in the opposite direction, as shown in FIG. 5.

Referring now to FIGS. 5-7, the first bending portion 113 is formed with an anti-skidding track 116 at a position facing the bottom surface 111, which allows a washer screw 300 with an anti-skidding surface is located by the anti-skidding track 116. Preferably, the anti-skidding track 116 may be pressed into a tooth form as shown in FIG. 7, and may also be pressed into a knurled track surface (not shown).

FIG. 8 illustrates a schematic diagram of an application scenario of the heavy duty girder 100 according to the present disclosure. The heavy duty girder 100 according to the present disclosure may assemble a modular structure at any height in directions of up, down, left, and right at the same time. As shown in FIG. 8, a plurality of heavy duty girder 100 are flexibly assembled into various extension structures by a plurality of bolt assemblies 200, washer screws 300, supports 400, connectors 500, saddle supports 600, slipping bars 700 and support angles 800.

The above-described embodiments are merely exemplary illustrations of implementations set forth for a clear understanding of the principles of the disclosure. Many variations, combinations, modifications or equivalents may be substituted for elements thereof without departing from the scope of the disclosure. Therefore, it is intended that the disclosure not be limited to the particular embodiments disclosed as the best mode contemplated for carrying out this disclosure, but that the disclosure will include all the embodiments falling within the scope of the appended claims.
